All 137 crewmembers have been evacuated.
127 left the ship on her liferafts, the remaining ten (incl. the captain) stayed onboard for another two hours until she was beached.
How the hell did they manage to ram a supertanker who had the right of way/traffic in calm seas?
Even worse, in one version of the story (there's a couple by now, and none by the Navy itself) they apparently managed to slip inbetween the tanker and the tugboat that was towing it out of the fjord.
It's also notable that different sources give different times for the accident - between 4:03 am and 4:26 am. The frigate turned on AIS at 4:03 am according to the Navy.
